Patent GB-109333-A (GB)
Title: Improvements in Automatic Controlling Means for Heating and Lighting Installations and such like.
Inventor: SAUNDERS SAMUEL
IPC: G04B23/08
Filed: 1916-10-24
Abstract: 109,333. Saunders, S. Oct. 24, 1916. Clockwork-actuated valves.-A device for actuating dampers, doors, electric switches, valves, &c., by means of an alarum clock is arranged so that a single winding of the alarum mechanism will suffice for a number of actuations, and also is provided with means to enable the apparatus to skip one or more days when necessary. The clock a is removably mounted in the door a<2> of the casing a<1> and has the winding-spindle of the alarmn mechanism fitted with a plate having two pins b<2> adapted to co-operate with a projection c<x> on the upper part of a release lever c acted on by a spring d. The release lever is formed in two parts, both of which are pivoted on a pin c' on a base-plate c<2>. The lower part c<1> has a notch c<5> adapted to engage a pin h<3> on a grooved wheel h, which is connected by weighted cords to the apparatus to be actuated, and which has a handle k<1> for resetting purposes. The upper part carries a pawl n adapted to rotate a ratchet m to bring a stop m<2> into contact with the lower part, after which both top and bottom parts move as a single lever. The stop m<2> is normally in contact with the lever; but when it is desired to miss a number of days, the pawl is lifted by hand and the ratchet rotated a number of teeth equal to the number of days. The Provisional Specification 718/17 describes a modification adapted to miss one day only, in which the pawl engages one of two pins on the lower part. The upper end of the release lever is guided in a slotted bracket j and has a projection c<3> adapted, on a forward movement, to slip past a knee-jointed member g on a lever e<3> normally resting against a stop e<4>, and on a backward movement, which occurs as soon as the pin b<2> leaves the projection c<x>, raises the member g and lever e<3>, causing the end e<2> to depress the alarum stop-mechanism f and so prevent the alarum mechanism from rotating more than is necessary to release the catch c<5>.
Patent GB-599012-A (GB)
Title: Improvements in or relating to fluid flow-dividing and flow-uniting valves
IPC: G05D16/18
Filed: 1944-08-08
Abstract: 599,012. Fluid - actuated valves. BENDIX AVIATION CORPORATION. Aug. 8, 1944, No. 15092. Contention date, Sept. 18, 1943. [Class 135] A fluid flow equalizing or proportioning device for dividing a flow or combining two flows equally or in proportion and applicable, e.g. to a hydraulic system including motors for operating the flaps or landing gear on aircraft, comprises a double piston valve member 80, 82 controlling the flow from a passage 42 to outlet passages 44, 46 or vice versa. For dividing and equalizing the flow from passage 42 the fluid acts upon a spring-loaded piston 48 which provides a throttling action and a drop of pressure into passages 56 and 58 leading to the ends 80 and 82 of the piston valve member respectively from where the flows pass through check valves 74 and 76 to the outlets 46 and 44. Passages 64 and 65 connect the passages 56 and 58 to the two sides of a piston 78 integral with the piston valves 80, 82. On an increase in flow in one line an increased pressure drop is obtained across the throttling piston 48 with a reduction of pressure on one side of the piston 78 which moves to close the passage in that line and open the passage in the other line and so equalize the flows. For combining two equal flows from passages 46, 44 to an outlet 42, the flows pass through check valves 70 and 72 and a back-pressure is built up in front of the throttling piston 48 in the passages 56 and 58, the piston 48 being moved to open against its spring by the pressure of the fluid acting through a passage 55 on to a flange 52. Any unbalance of flow produces an unbalance in the back-pressures in the passages 56 and 58 which acts upon the piston 78 to move the valve 80, 82 to correct the flow as before. A proportionate flow can be obtained by arranging the throttling passages provided by the piston 48 of different sizes or by providing the piston 78 with unequal areas on its two sides or providing a loading spring on one side.

Title: Improvements in and relating to breathing apparatus
IPC: A62B9/00
Filed: 1955-05-27
Abstract: 783,565. Respiratory appliances. HUMBLET, F. May 27, 1955 [May 31, 1954; May 11, 1955], No. 15423/55. Class 81 (2). An open circuit, underwater breathing appliance has two-stage air pressure reduction, the second regulator being mounted on the face mask so as to be subject to the same pressure as the nose and mouth of the user. A mounting plate 1, Fig. 1, carries two air bottles 2 in stirrups 83, and their outlets are attached to a union member 6, from which air is passed to a primary regulator 6a and thence through a pipe 7 to the secondary regulator mounted on the face mask. The outlet 75, Fig. 9, from the air bottle 2 is secured to the connection member , 6 by a hand wheel 77 and air pressure then lifts a valve 47 for air to pass into the conduit 46 and thence through a check valve 43. This valve is spring-loaded and adjusted by a screw 44a and air passes through it to tube 41a and to a primary regulator. When an air bottle is near exhaustion the valve may be positively lifted off its seating by a pin 50 on a screw 49 or a by-pass to tube 8 may be opened by a manually-operated needle valve. The primary regulator comprises a valve 54, Fig. 8, controlled by a diaphragm 59, the outer face of which is exposed to ambient pressure and to the thrust of an adjustable spring 60. Air at reduced pressure passes through a duct 63 to a pipe 7 leading to the secondary regulator. The secondary regulator is mounted on the face mask and comprises a valve 18, Fig. 3, which is lifted from its seating by excess ambient pressure on the outer face of a diaphragm 14. Air enters the casing 13 through this valve from the connection pipe 7 and passes to the face mask 10 through an inhalation valve 37. The casing 13 also encloses an alarm whistle which is sounded when the air pressure received from the primary regulator falls to a level sufficiently low for a loaded valve, supplying the whistle, to open. The alarm may also be actuated from the valve 43, by the drop in pressure when the air cylinder in use cannot maintain this valve fully open.
